I'm a little stuck... Click here to teach me more about this clue!

'cleaner gets sick pensioner to eat nothing' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'cleaner gets sick pensioner to eat nothing' is the wordplay.
I cannot quite see how this works, but
'cleaner' could be 'soap' (soap is a kind of cleaner) and 'soap' is found in the answer.
'nothing' could be 'o' (looks like zero - 0) and 'o' is found in the answer.
'sick' could be 'barf' (synonyms) and 'barf' is located in the leftover letters.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?

(Another definition for bar of soap that I've seen is " Cake in a dish?".)

I've seen this clue in The Guardian.
